The bsc_msc_data->rtp_base has been unused ever since we introduced the exernal
MGW in osmo-bsc [1]. The vty command also still exists. Deprecate the vty
command, remove the member.

We decode the mesage and print it to the log files at ERROR log level.
We also count it in the BSSMAP message counters. There is not much
else we could do about it.

We already have counters for Rx side, now we also count Tx side.
See comments in the msc_ctr_description array implementation for
the details.

The struct member struct bsc_msc_data->is_authenticated is set to true
permanently. This is a leftover from the sccplite implementation and can
be removed now.

Old osmo-bsc-sccplite already supported this, but in the migration
over to libosmo-sigtran and to real 3GPP AoIP, this functionality
got lost.
We now create a UDP proxy socket. Any MGCP commands received via IPA
from MSC (or rather: bsc_nat) are retransmitted to the MGW via UDP on
this socket. Any responses back from the MGW received on the UDP
socket are retransmitted back to MSC/bsc_nat as MGCP inside the IPA
multiplex.

In Change-Id If6d40b2407b87aad2227ea7f15533ef01a3771b3 we introduced
the support for both octet-aligned and bandwidth-efficient mode, and
added a related VTY option about it.
However, we accidentially also changed the default behavior. Without
any explicit configuration, we should behave just like we behaved all
those years before: Continue with octet-aligned mode.

When the user sets no codec-list in the msc node, the configuration will
end up with an empty codec list. This is a useless configuration. There
should be a sane default setting.
- Set all possible codecs as default for codec-list

The bsc_msc_connection dates back to the old pre-libosmo-sigtran
days, and 90% of the field members weren't used at all (even the
new sigtran specific ones!). Let's merge what remains into struct
bsc_msc_data.
As a side effect, the already dysfunctional "dest A.B.C.D" VTY
command has been removed from the MSC node.
There's quite a bit of fall-out in the CTRL interface, which was
the code with strongest ties to bsc_msc_connection. This was
resolved by properly porting CTRL handling over to libosmo-sigtran,
meaning that an IPA/SCCPlite connected MSC can now again send CTRL
GET/SET commands, and can also receive those selective few TRAPs
that old osmo-bsc-sccplite also sent to its MSC[s].

osmo-bsc_nat is too heavily tied into legacy SCCPlite code, as it
is not using libosmo-sigtran/osmo_ss7 so far. It's also full of
customer-specific code and it's shared use of some libbsc code here
has been complicating osmo-bsc development.
The current plan is to continue to use osmo-bsc_nat from openbsc.git
for those legacy users that need it, and not use osmo-bsc_nat in
new 3GPP AoIP setups. Should we ever get a strong demand for an AoIP
based bsc_nat, we can still revisit this later.

We used to have hard-coded M3UA. Let's allow the user to configure
this per MSC using a new "asp-protocol (m3ua|sua|ipa)" VTY command.
For SUA this should just work 1:1 without any trouble. For IPA,
this of course only changes the underlying transport without reflecting
the various differences in terms of BSSMAP ASSIGNMENT, MGCP handling,
etc.

There is a lot of dead code in osmo_bsc_msc.c that used to handle
the IPA multiplexed SSCP lite A interface.
- remove portions of the dead code
- remove IPA Ping related VTY commands

Add 3-digit flags and use the new RAI and LAI API from libosmocore throughout
the code base to be able to handle an MNC < 100 that has three digits (leading
zeros).
The changes to abis_test and gsm0408_test show that this code now handles
3-digit MNC correctly, by not dropping the leading zero as 0xf in the encoded
PLMN.
Re-implement CTRL commands 'mcc', 'mnc' and 'mcc-mnc-apply' to preserve the
presence of the third digit of the MNC. Always reply with all leading zeros.
Adjust the expected results in ctrl_test_runner.py, to show that it works.
In VTY and CTRL, the parsing of MCC and MNC is inherently made stricter by use
of osmo_{mcc,mnc}_from_str() -- they will no longer allow surplus characters
and detect errno returned by strtol() (in contrast to atoi()).

libosmo-sccp is the old sccp-lite-focused SCCP implementation that we
used before libosmo-sigtran was created. The new osmo-bsc in this
repository is using libosmo-sigtran and shouldn't be using parts of
libosmo-sccp anymore.
We only keep it around in configure.ac and Makefile.am for osmo-bsc_nat,
which is not even built in this repository anymore (or 'again yet'?)

This was originally a long series of commits converging to the final result
seen in this patch. It does not make much sense to review the smaller steps'
trial and error, we need to review this entire change as a whole.
Implement AoIP in osmo-msc and osmo-bsc.
Change over to the new libosmo-sigtran API with support for proper
SCCP/M3UA/SCTP stacking, as mandated by 3GPP specifications for the IuCS and
IuPS interfaces.
From here on, a separate osmo-stp process is required for SCCP routing between
OsmoBSC / OsmoHNBGW <-> OsmoMSC / OsmoSGSN
jenkins.sh: build from libosmo-sccp and osmo-iuh master branches now for new
M3UA SIGTRAN.

This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.
